DFS Lag |
|
|
Hey guys, I looked through quite a few pages of stuff and did a couple quick
searches as well. To no avail. So here I am posting!
Pretty simple setup here. We have a Windows 2000 server that is hosting a
DFS for this site, it is on a Windows NT domain (/cry) but really the only
thing we are doing is using the DFS to make it easier when we map the drives
to switch data between servers and stuff, so it is all just directly mapped
stuff and everything else. No crazy FRS (note NT domain) or for that matter
ANY replication.
The funny thing is it used to be (few weeks ago I guess) working just fine.
Now however it has gotten to the point where you open My Computer (the DFS
links are mapped to drives on the client) and you get a lag of about 20
seconds, and then as you browse through the drive you get lags opening
folders at random every minute or so... No network traffic is coming through
to the client (Windows XP SP1), no network errors or anything so my first
assumption is that the DFS is having some weird issues and maybe
authentication issues that go over the WAN to our PDC (oh did I mention this
computer is also a BDC?) or something. Otherwise possibly it could be some
corruption in the DFS structure but I imagine that would break a lot more
stuff and would be something we would notice more than just a bit of lag
about.
If you took the time to actually go through that whole post and are actually
going to offer up some advice I thank you..
My first step is to get DFSUtil I think and start troubleshooting there but
really I just have always had trouble finding appropriate utilities to get to
the bottom of DFS issues, any suggestions would be great!
Thanks,
Joe |

<cough> bump <cough>
Bless me, I must be coming down with something!
So anyone have any input in regards to below? Or should I just sit here in
the frying pan waiting for the boiling oil to come down?
This honestly is a problem I have had before at another site as well, FYI,
so it seems like it would be a pretty common thing around here...

Couple of things:
Run some DFS monitoring such as DFSUTIL, SONAR, ULTRASOUND.
Run a network trace when this is happening.
Check, and then check again your AD Sites and Subnets.
What are the clients? Is this uniform across all clients or just some? One
site or many?
Any more info. the better.
(Sorry for the delay - I was out at Redmond and was ill when I returned ;-)

DFSUtil fails on doing most tasks with an RPC error:
C:\>dfsutil /domain:franticnet /view
Microsoft(R) Windows(TM) Dfs Utility Version 4.0
Copyright (C) Microsoft Corporation 1991-2001. All Rights Reserved.
No roots exist on domain franticnet
System error 1722 has occurred.
The RPC server is unavailable.
This command just hangs there till I abort.
C:\>dfsutil /root:\\server1\dfs /view
The one below here returns an error:
C:\>dfsutil /server:\\server1 /view
Microsoft(R) Windows(TM) Dfs Utility Version 4.0
Copyright (C) Microsoft Corporation 1991-2001. All Rights Reserve
No roots exist on machine \\server1
System error 1733 has occurred.
The tag is invalid.
So troubleshooting via DFSUTIL is pretty much a waste of time.
SONAR and ULTRASOUND are FRS troubleshooting utils I believe. Dont run
FRS, dont need them.
Network Trace? You mean capture packets? I can trace/ping the server
the whole time, connectivity is definitely not an issue.
I also did capture packets and saw some errors in there, wouldnt know
how to go about posting that though.
No AD so no Sites/Subnets.
The clients are all XP SP1 and the server is W2kAS.
Thats about it!

Those RPC errors are strange, especially if you are not experiencing other
network issues. I would run DCDIAG /V /C /E and NETDIAG /V on one of your
DCs to see if all of the DNS SRV RRs are ok. As this site-based stuff uses
those. You might also want to have a poke around manually, to make sure
there's no stale records under incorrect sites, etc. I've seen this happen
before.
